Title: Semiconductor device
Inventor: KANAMORI SHUJI
IPC: H01L29/72
Filed: 1986-11-10
Abstract: PURPOSE:To reduce the area of a base and to lower the capacitance sharply by a method wherein a base contact region is not located inside a collector junction region. CONSTITUTION:A base region 2 of low concentration is formed selectively at an insulating film 7 located on an n-type semiconductor substrate 1. During this process, it is preferable that the concentration of a base is set by about one order of magnitude lower than the concentration of the base located in an operating part. Then, the epitaxial growth is executed on the main surface of the semiconductor substrate at the concentration of the base region 3. During this process, the insulating film 7 becomes polycrystalline. The side wall of the base is etched by making use of a photoresist material or an insulator 8 as a mask. In addition, a base contact region 4 is formed by making use of the photoresist material or an insulator 9 as the mask. The insulator 7 is formed on the main surface of the semiconductor by a CVD method; a contact hole for an emitter and the base is made; N-type polysilicon 6 containing an impurity for emitter diffusion is grown. Through this constitution, because the side walls 3, 4 of the base are surrounded by the insulator 7 and no depletion layer is formed, it is possible to lower the capacitance at the side walls.

Title: Photosensitive material drying device
Inventor: KAWADA KEN
IPC: G03D15/04
Filed: 1989-10-17
Abstract: PURPOSE:To dry a photosensitive material in a short time and to prevent image trouble such as the deformation of the photosensitive material from being caused by giving conveyor rollers air permeability. CONSTITUTION:The conveyor rollers 54 and 56 have the air permeability. Consequently, when air nearby the surface of the photosensitive material 12 is discharged by an air suction part 81 behind the conveyor roller 54 and 56, the air circulates excellently through the conveyor rollers 54 and 56. Further, the air receives small resistance when discharged since the conveyor rollers 54 and 56 have the air permeability, and a disturbing flow or negative pressure is hardly generated, so that the air flows smoothly. Therefore, moisture- containing air nearby the surface of the photosensitive material 12 is discharged efficiently and the photosensitive material 12 is conveyed properly without fluttering. Consequently, the photosensitive material is dried in a short time and image trouble such as the deformation of the photosensitive material is precluded.

Title: Structure of semiconductor mounting component
Inventor: TANAKA HIROTAKA
IPC: H01L21/60
Filed: 1988-10-25
Abstract: PURPOSE:To make possible the prevention of a short circuit between a wire and the outside wire of a die pad by a method wherein an insulator is formed on the outer peripheral part of the die pad on a lead frame. CONSTITUTION:An insulator 5 is formed on the outer peripheral part of a die pad 2. Even if a bonding wire 4 is liable to cause a short-circuit between the pad 2 and the wire 4, the insulator 5 works as a stopper to prevent the short-circuit. As the pad 2 has electrically the power potential of a die 1, a short-circuit between this power potential and a signal, whose polarities are directly opposite to each other, or other power supply becomes a lethal defective in a semiconductor product. In such a way, the insulator 5 enables a short circuit between the pad 2 and the wire 4 to make impossible physically. Accordingly, an electrical short-circuit is made to zero.

Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a power source circuit realizing an electrooptical device in which the display unevenness caused by ripples which are generated in a driving voltage does not appear. SOLUTION: In this power source circuit, when the number of pieces of a reference signal which are generared in a vertical scanning period (frame) is an even number, a timing when a driving voltage is generated is shifted by a time equivalent to one cycle of a latch signal (the reference signal) before and after the vertical scanning period is changed over. As a result, ripples which are superposed for every vertical scanning period are cancelled. For example, when this power source circuit is used for a liquid crystal display device, the display unnevenness can be suppressed.
